To calculate density, both volume and mass must be measured.
d - density
m - mass
V - volume
_________
d = m/V

A cell membrane does not actually maintain homeostasis by itself. The term homeostasis refers to maintaining a relatively stable internal environment inside of a multi-cell organism.
Answer:
17.6% is the percentage error
Explanation:
The percentage error is used to determine accuracy of a measurement (That is, how closely is the measure to the real or theoretical value). The equation is:
|Measure - Real| / Real * 100
In the problem, the measure was 22.7cm³ and real value is 19.3cm³. Solving for percentage error:
|22.7cm³ - 19.3cm³| / 19.3cm³ × 100
<h3>17.6% is the percentage error</h3>
